NullpointerException in LexoRankBalanceRankInfoService Edited

As described in one can access https://<jira-base-url>/rest/greenhopper/1.0/lexorank/balance to get balancer status. Instead I get a NullpointerException.

The base problem I try to fix is which in one project occurs 100% while is not so noisy in others.

Any suggestions on how to proceed from here?

This did the trick:

alter table "AO_60DB71_LEXORANK" alter column "RANK" type character varying(255) collate pg_catalog."POSIX";
